ENUM: Mapping the E.164 Number Space into the DNS

Many communications networks are constructed for a single form of communication, and are ill suited to being used for any other form. Although the Internet is also a specialized network in terms of supporting digital communications, its relatively unique flexibility lies in its ability to digitally encode a very diverse set of communications formats, and then support their interaction over the Internet. In this way many communications networks can be mapped into an Internet application and in so doing become just another distributed application overlayed on the Internet. From this admittedly Internet-centric perspective, voice is just another Internet application. And for the growing population of Voice over IP (VoIP) users, this is indeed the case... more

Put Free Expression on the Internet Governance Forum Agenda

The Internet Governance Project has joined free-expression advocacy organizations Reporters Without Borders and Article 19 to push for including Internet censorship and filtering problems on the agenda of the first meeting of the new Internet Governance Forum (IGF), a multistakeholder deliberation body created by the World Summit on the Information Society... more

Identity, ICANN, and Public Meetings

Ok, so I had a day in Wellington that was not busy with other things so I thought I'd wander over to the ICANN venue and sit in on the PUBLIC Forum... I saw friends on the walk over and we entered the venue, chatting about several different things. They pulled out their badges. I didn't have one. They were admitted, I was denied entrance... more

Reporting To God

"GOD, at least in the West, is often represented as a man with a flowing beard and sandals. Users of the Internet might be forgiven for feeling that nature is imitating art — for if the Net does have a god he is probably Jon Postel" (The Economist, Feb. 1997) David W. Maher, Senior Vice President, Law and Policy of Public Interest Registry (PIR) offers his reminiscence of the early days of the Internet and attempts made to restructure the Domain Name System — an article he has entitled 'Reporting to God'. more

MicroID: A Microformat for Claiming Ownership

This morning I learned about MicroIDs from Doc Searls. Jeremy Miller has proposed MicroIDs as a microformat that "allows anyone to simply claim verifiable ownership over their own pages and content hosted anywhere." A MicroID is a hash of two hashed values. The first is a verified communication ID. The second is the URI of the site that the content will be published on. You end up with a unique, long string of gibberish that can be put in the header of a Web page or even wrapped around one part of a page... more

Testing IDNs

Internationalized (non-ascii) domain names (IDN) are a key issue for ICANN. Yesterday, the Board completed two days of workshop presentations about various matters (IANA, security, GAC relationships), and we were briefed on the IDN testing that is planned. I thought it might be useful to make clear the distinction between the tests (which are testing mechanisms for IDNs) and the very difficult policy questions that confront ICANN. As several people explained to me yesterday, they're different. more

Latest Turn of Events on .XXX, from ICANN Wellington

As the ICANN's week-long meeting in Wellington, New Zealand is now fully underway, the approval of the proposed .XXX top-level domain (TLD) continues to remain a key topic of discussion and its eventual approval yet uncertain. The .XXX TLD was widely expected to receive its final approval at the ICANN's last meeting held in Vancouver about 4 months earlier but the discussion was unexpectedly delayed as the organization and governments requested more time to review the merits of setting up such a domain. Stuart Lawley, president of the would-be .XXX operator ICM Registry LLC offers his comments from Wellington. more

Telecom Impact on Per-Capita GDP

My presentation at VON was focused on availability (aka presence) and contextually-aware communications, but I did begin with a brief mention of subjects I'm passionate about and I ended with my typical closing comments about telecommunications... Apparently this struck a chord with several people who came up to me afterwards asking about how they could help the spread of telecom to developing countries and did I have references for my statements about telecom is good for mankind? more

Freedom to Connect

Over the last ten years, Andrew Odlyzko has been writing about a pricing algorithm that would assure reasonable service levels at reasonable prices. If you're going to F2C, you might want to read that brief article or this slightly more complex one to learn (or refresh your sense of) PMP -- Paris Metro Pricing models to deal with network congestion. You'll also get a sense of why throwing bandwidth at the network will not be sufficient. Here's a great article from 1995... more

Telecom Policy Review Panel Calls For Net Neutrality Legal Safeguards

The Telecommunications Policy Review Panel report [Canada] was released yesterday and while the immediate reaction will no doubt focus on the recommendations for a market-oriented approach with significant changes to the CRTC, I would call attention to three other recommendations gleaned from reading the executive summary (the full document is nearly 400 pages). more

ICANN Meeting: The Road to Wellington

What would it take for this upcoming meeting to be a success? I am a big believer in ICANN's core principles, and in the forum it provides for private self-governance of domain names and numbers. I think the ICANN model continues to have great potential as a form of governance. For this meeting to be a success for me, personally, I'd like to see those core principles made more visibly operational -- or at least see a start made on this effort. I'm putting a stake in the ground with these posts, and we'll see whether progress happens or not. more

Report on DNS Amplification Attacks

In this newly released paper Randal Vaughn and Gadi Evron discuss the threat of Distributed Denial of Service (DDoS) attacks using recursive DNS name servers open to the world. The study is based on case studies of several attacked ISPs reported to have on a volume of 2.8Gbps. One reported event indicated attacks reaching as high as 10Gbps and used as many as 140,000 exploited name servers. more

What If They Simply Made Communications Technology Better?

Rob Hyndman has a pointer to Mark Cuban's latest: Think the Internet Will Replace TV? Think Again. Cuban's post can be summarized as: Today's broadband networks are too slow. The insatiable appetite for on-demand rich media content will soon overwhelm them. Telco's aren't putting in upgraded networks quickly enough to meet that demand. Cuban also provides some facts and figures to back up that claim. In the comments, readers have a number of viewpoints, including the view that Mark has ignored cable, and that cable can provide the required speeds and feeds... more

CIRA Suspends Participation in ICANN

The Canadian Internet Registration Authority (CIRA) has issued a public letter to ICANN calling on the organization to follow accountable, transparent, and fair processes. Until the concerns are addressed, CIRA says it is suspending its voluntary contributions to ICANN... more

Skype: When Good Press Releases Go Bad

Burton Group issued a press release last week announcing the conclusions of my recent report on Skype. I thought the release clearly stated our conclusions on Skype, which essentially were that there are indeed security and management concerns that enterprises ought to be aware of, but that those risks may be outweighed by the business benefits offered by the use of the application, and that enterprises must carefully weigh risk vs. reward when evaluating Skype usage. more
